Optimization of TIG Welding on 304 Stainless Steel and CR1 Grade Mild Steel using Taguchi Method and Analysing Defects by Radiography Testing

The main focus of this paper is to study the effect of TIG welding on stainless steel and mild steel plates and analyzing the defects by radiography testing using three different paramenters like current, voltage & gas flow rate (Argon Gas) as shielding & having dimensions of 100 mm X 100 mm X 4 mm. TIG welded plates majorly used in industries purpose. The welding of dissimilar metals is most useful in structural applications. But the difficulty arises due to welding such plates because of the loss of carbon from mils steel and precipitation of chromium in stainless steel during welding. TIG welding is best suitable process used to control these problems occur during welding on base metals joints. Here main purpose of this paper is to discuss about effect of welding on MS and S.S plate and study the result like hardness, tensile, bend test etc. In this experimental test it is seen that there is nothing problematic to weld such plates carry different composition. All result shown satisfactory. It is evaluate that TIG welding perform best on S.S and MS welding.
